Abstract

[ problem ] to provide a travel drum that ensures forward and downward visibility and ensures a field of view during travel. The traveling drum, which makes visible from the front and below, ensures the view of the player during traveling by eliminating all or some of the members of the main body of the drum, or by employing a transparent member.

Description

Running drum visible from the front and below

Technical Field

The present invention ensures visibility of a player who travels a drum, and relates to a drum that makes it easy to travel.

Background

In terms of musical composition, traveling drums require their size range to be 18 "to 40". These drums are not sex-differentiated, they are all suspended above the body of the player as shown in fig. 1, and they are used for performance while traveling.

Disclosure of Invention

Technical problem to be solved

When the player 0 travels, the drum in the region 1 where the visibility of the player 0 is obstructed to produce a blind spot, as shown in fig. 1. Therefore, since the player 0 cannot see his legs and confirm the direction of movement, the motion of traveling during the performance becomes very dangerous. Alternatively, in some cases, accompanying personnel are also needed to monitor movement.

Means for solving the problems

1. The present invention adds the following improvements to the drum in order to solve the above problems. Holes 5, 6 and 7 as shown in fig. 12 made on a part of the body of the drum 100 make the front and lower visible.

2. Even if the transparent member as 12 in fig. 14 is added at the position where the holes as 11 in fig. 13 are located and even if the holes are made, the reduction of the acoustic performance of the drum is prevented.

3. As a member forming a part of the main body of the drum 300 in fig. 15, a transparent member such as 8, 9 and 10 in fig. 7 and 8 ensures front and lower visibility.

4. The transparent member 20 in fig. 18 mounted along the circumference of the middle stage portion of the main body 2 of the drum 500 in fig. 17 creates a structure that can ensure the front and lower visibility 1.

5. The drum 700 of fig. 19 is configured with side members 18 and 19 and brackets (lugs) 22 on both sides of the drum 600 to fix the drum head (head) as the drum's striking surface. A portion 21 without a hard member is formed at the middle section of the main body 2 of the drum. The portion 21 is configured to ensure front and downward visibility. If the members 18 and 19 connecting the drum heads (drum heads) 14 and 15 are made of a transparent member, optimum visibility can be ensured.

Advantageous effects

According to the present invention, the following effects are provided.

1. Since the player can see the front and the lower, the player can travel safely while playing.

2. The accompanying person while moving becomes unnecessary.

Detailed Description

The invention will be described in detail with the aid of practical examples in the following figures.

Performance example 1 of the present invention

Top end of window body

Fig. 1 shows a player 0 who hangs a conventional drum 100 from the front. In such an embodiment, as shown in fig. 1, when the player 0 performs and travels simultaneously, a blind spot is generated for the player 0 because the main body 2 of the drum 100 is directed toward the front of the face of the player 0 as shown in fig. 2. For this reason, when the player 0 generally travels, they must generally travel mainly by predicting the forward and downward visibility based only on the surrounding environment, which makes the player 0 very difficult to perform and also creates a potentially dangerous situation.

In addition, in the case where the player 0 carries the drum 100 before or after the performance, a follower is generally required. The present invention is intended to eliminate the necessity of a follower due to the movement, so as to eliminate such blind spots, thereby ensuring the visibility of the player and enabling the player to travel safely while he is playing.

The following three (3) methods are considered to ensure visibility.

1. As the drum 400 in fig. 9, a transparent member is employed as a main body material of the drum.

2. As in the drum 200 in fig. 6, the holes 5, 6 and 7 are formed at some positions on a part of the main body 2 of the drum where the visibility of the player 0 is blocked, or the transparent members 11 and 12 are placed on the opening of the drum.

3. As the drum 300 in fig. 7 and the drum 500 in fig. 10, the transparent members 13 and 20 are employed on a part of the main body 2 of the drum, in which the visibility of the player 0 is interrupted.

4. As the drum 600 in fig. 19, a structure employing the gap 21 is formed without using any member that blocks the visibility of the player 0 along the circumference of the middle step portion of the main body 2.

With method-1, the problem can be solved assuming that a member similar to an acrylic material is used as the drum 400 in fig. 9. However, the drum size as previously described is typically in the range of 18 "to 40". As the size of the drum 100 increases, there is also a problem that the drum 100 becomes too heavy to be carried regardless of gender distinction even if visibility is ensured. This is because acrylic materials are generally very heavy compared to wood.

With method-2, as shown in fig. 3, by forming an opening 5 on the player 0 side and an opening 7 on the opposite side of the player 0 in the main body of the drum 200, it is possible to ensure front visibility of the player 0 in fig. 3. In the same manner as described above, by forming the opening 6 in the main body 2 of the drum, the downward visibility 4 can also be ensured.

This treatment causes acoustic problems. In the case of the conventional drum 100 in fig. 1, when the player 0 strikes the head (head) 14 as the striking surface of the drum with the striker 16, air that cannot escape inside the drum 100 is forced by the ears toward the head (head) 15 on the opposite side, and the head (head) 14 as the striking surface of the drum is pushed out because the forced head (head) 15 of the drum is restored with its restoring force. This rich action causes the drum's powerful sound to be emitted and gradually attenuated.

In fig. 3 the drum of the invention is provided with holes 5, 6 and 7 located on the body of the drum 200. With respect to a drum for playing on a performance, the intended object of the present invention can be fully achieved. However, because the interior air escapes through the three holes on the drum 200, the volume of the drum sound is reduced and its timbre becomes worse. Closing the openings of the holes 5, 6 and 7 with the transparent member 11 or 12 prevents deterioration in the timbre of the drum. Further, it is needless to say that the shape of the above-described transparent member is not limited to a circle or a square, but any shape may be used if visibility is ensured.

With method-3, as shown in fig. 15, the front visibility of the player 0 can be ensured by using the square transparent portions 10 and 8 on the main body 2 of the drum 300. In the same manner as described above, the downward visibility can also be ensured by using the square transparent member 9 on the main body 2 of the drum. To manufacture the drum 300, the body 2 of the drum is made by arranging a transparent member 13 on each of the openings 8, 9 and 10. In order to secure strength and maintain the circular shape of the drum, a reinforcing material 17 or the like as shown in fig. 15 may be used. Furthermore, it goes without saying that the positions of the openings are not limited to openings like 8, 9 and 10, but any positions of the openings are possible if the desired visibility is ensured.

With method-4, as shown in fig. 17, the transparent member 20 is sandwiched to fit in the body break of the drum 500, with the two members 18 and 19 attached to the heads (head) 18 and 19, and the brackets (lugs) holding the heads (heads) 14 and 15 as the striking surfaces of the drum. The transparent member 20 ensures front and lower visibility 1. Further, it goes without saying that the position of the transparent member is not limited to the interruption of the drum and the circumference of the drum, but any shape is usable if the required visibility is ensured.

With method-5, the body midsection of the drum 600 is formed with the gap 21 without using the transparent member 20. The drum 600 is constituted with the brackets (lugs) 22 to fix the head (head) and the members 18 and 19 and further the drumheads (skins) 18 and 19, whereby the front and lower visibility 1 thereof can be ensured. Furthermore, it goes without saying that the position of the gap is not limited to the main body midsection of the drum, but any position is possible if it ensures the required visibility.
